This is the real thing about investing in Bitcoin and even in other investments. Even if you have money and the capacity to invest, not all of them will think that investment is good until they realize it, and much more on students. Because we all have different priorities and wants, especially for students they more likely prefer good vibes and spending money for enjoyment but are skeptical about future plans.
Indeed, it was regretful OP but there is perfect timing when it comes to investment. As a student, you better focus on studying and saving, just consider investing when you are fully ready. Investing is not all about money and capital and proper preparation and knowledge.
Investment is a choice, it doesn't really matter how convincing our words are to people about investment, what matters is individual interest which surpass every other thing, not everyone will think towards investment may be because of lacking of understanding and interest.
It not easy for a student to have the mindset of investing in Bitcoin for many reasons, lets not forget that pair group has much influence on student even when the money is available to invest such student may not deem it necessary to invest based on misinformation from some folks, personally I don't see anything wrong if a student doesn't want to invest in Bitcoin because i believe that there are stages of things in life, individuals should be allowed to take some certain stands in life, bitcoin is for people that are interested and prepared to take action towards investnig in Bitcoin, I think there is know much big deal about that.
